CHICAGO (CBS) — R&B singer R. Kelly left his Chicago studio and turned himself in to Chicago police Friday night ahead of a bond court hearing expected for Saturday afternoon. The star has been charged in Cook County with 10 counts of aggravated criminal sexual abuse.

The singer exited his West Side studio around 7:30 p.m. to a horde of media, giving a quick salute as he came out the door. He ignored requests for comment. He got into a black van and was taken to CPD’s 1st District police station.

Following the arrest, Kelly’s attorney Steve Greenberg spoke to the media, slamming the charges.

“I think all the women are lying,” he said. “Unfortunately the State’s Attorney has now succumbed to public pressure, to pressure from grandstanders like Michael Avenatti and Gloria Allred, and brought these charges. Mr. Kelly is strong. He’s got a lot of support, and he’s going to be vindicated on all these charges, one by one if it has to be.”

Cook County State’s Attorney Kim Foxx said Kelly was indicted on charges of sexually abusing four victims. The charges date back as far as 1998. Illinois has no statute of limitations on child sex abuse charges.

Nine of the counts against Kelly specify the victim was between 13 and 16. One count did not specify any ages. The charges are Class 2 felonies.
